Reading and displaying tabs in PHP

I read and display a file this way:

<some code here>
while(!feof($file)) {
$number++;
$result .= "<tr><td width=\"11\">$number.</td><td>". fgets($file) ."</td></tr>";
}
<some code here to finish the html table>
echo $result;

The problem is that when the table is displayed, tabs are not displayed. Thereby, the structure of the text, if tabs are used, is not correct.

By tab you mean the whitespace \t ? Your function fgets($file) gets only the string values so reading the file:
"This is just a text."
will get [this] [is] [just] [a] [text] (without a tab after "is").

Hope this helps

$result ='<table "width=100%">';
while(!feof($file)) {
$number++;
$result .= "<tr><td width=\"11\">$number.</td><td>". fgets($file) ."</td></tr>";
}
$result ="</table>";

echo $result;

Raods Roads: I need to display also the tabs. How would I do that?
shinug: you replaced my pseudocode(if you can call it that), with real code. That was not my intention :)

Can you post a sample of that text file ?

Shinesh Premrajan

Try either of these, as the text file need to be binary safe, b and t tags cane be used for such cases.

$handle = @fopen("test.txt", "rb");

$handle = fopen("test.txt", "rt");

Hope this helps

FYI,

str_replace("\t", "   ", $text);

wont pickup the \t in your text it .. :-)

The line I ended using was:
$result .= "<tr><td width=\"11\">$number.</td><td>". str_replace("\t", "   ", fgets($file)) ."</td></tr>";

It worked with me.
Why did you suspect that it wouldn't work? Just curious..
